    Southwest Airlines has created an initiative to equip each aircraft with Required Navigational Performance (RNP), which is designed to conserve fuel and reduce carbon emissions. 90% of Southwest aircraft are also equipped with winglets, which reduce fuel consumption by 2.5%. Another fuel saving initiative is controlling ground idle speeds, which saves 3.1 gallons of fuel for each hour the plane is idling.
